# AdMinder Redirect Script V3.1 Copyright 2002

############################################################################
##### OVERVIEW #############################################################
############################################################################
 
# This simple script allows you to use your own domain name in all of 
# your tracking URLs, and you only need to set this up one time. This
# script will simply redirect all traffic to the appropriate AdMinder
# URL based on the username and adcode provided, as explained below.
#
# So now, instead of using tracking URLs like this in your ads:
#
# http://www.adminder.com/c.cgi?username&adcode
# 
# You can use your own domain in your tracking URLs like this:
#
# http://www.yoursite.com/go.cgi?adcode
#
# No one will ever know you are using the AdMinder tracking system!

##### INSTALLATION #########################################################
############################################################################
 
# The simple instructions below should work fine for you. All servers
# are different though, so if this doesn't work for you please consult
# your webmaster or system administrator - they will know what to do.
#
# 1. Edit the 2 variables in the next section below.
#
# 2. Rename this file to any valid CGI script filename, based on your
#    server's configuration. Generally the file must end with .cgi or
#    .pl so a good filename would be "go.cgi", "redirect.pl", etc.
#
# 3. Upload this file to any directory that can run CGI scripts. Some
#    servers allow CGI scripts in any directory, while others require
#    all CGI scripts to be in the "cgi-bin","cgi" or other directory.
#
# 4. CHMOD this file to 755 - otherwise known as setting permissions.
#    This step simply allows your new script to be executed properly.
#
# 5. Done! Depending on the filename and where you uploaded it, your
#    tracking links will now look like the following:
#
#    http://www.yoursite.com/redirect.cgi?adcode
#    http://www.yoursite.com/cgi-bin/go.pl?adcode
#    etc.

##### EDIT THESE 2 VARIABLES ###############################################
############################################################################

# Replace xxx below with your AdMinder Username
# Example: $username = "myusername";

$username = "xxx";

# Replace xxx below with the URL of your homepage
# Example: $homepage = "http://www.mysite.com";

$homepage = "xxx";

$adcode = $ENV{'QUERY_STRING'};

if ($username =~ /^[a-zA-Z0-9]{4,12}$/ && $adcode =~ /^[a-zA-Z0-9]{1,10}$/) {

	print "Location: http://www.adminder.com/c.cgi?$username&$adcode\n\n";

}

	print "Location: $homepage\n\n";
